Innovex Float Shoes and Float Collars utilize the proven High Flow (HFX) Plunger Valve for applications where high flow rates, abrasive LCM materials and/or extended flow rates are encountered. All valves have HNBR coated Phenolic plungers for good wear resistance and optimum sealing of the valve. The Innovex HFX valve can be configured to work as a straight check valve or may be ordered with the auto-fill option, which allows for filling of the casing during run in operations. The 305 Series is available in 2-1/2″ valve size and the 315 Series is available in 3″ valve size – and have been tested to API Specification 10F.
